Insert a subreport in main report. Subreport has different dataset than main report but same datasource CRM Online Microsoft Visual Studio Business Intelligence Development Studio 2008 (BIDS)

I am attempting to create what I thought would be a very basic report in BIDS however I cannot seem to establish the parameters correctly.  I want to create a main report called "Report 1" that pulls up all of our accounts based on the value in [new_job] and then have a subreport that includes the account notes from "Report 2".  I have successfully created each individual report and run them, however I cannot get a subreport to work in the main report.  I know this is probably a newby question but how do I do it?

Report1 - dataset1 field [new_job]
Report2 - dataset2 field [LE_5A90BA7D_new_job], this will be a subreport to "report 1"


[new_job] and [LE_5A90BA7D_new_job] contain the same information in CRM Online.  How do I tell the report that these are the same?

Thanks for your help!
